2017-5-1 is a combination reaction that produces Fe 2 O 3 from its constituent elements—Fe and O 2. Combination reactions do not have to combine elements, however. The chemical equation. Fe2O3 + 3SO3 → Fe2(SO4)3. shows a combination reaction in which Fe 2 O 3 combines with three molecules of SO 3 to make Fe 2 (SO 4) 3.

Chemical reactions (or chemical changes) involve collisions between molecules which rearrange atoms or bonds within molecules, changing the overall composition. They are far too small to see directly with the naked eye. Instead, we make observations which are

A chemical reaction is the process in which reactants react chemically and convert into products by chemical transformation. For example – Respiration – we inhale oxygen which reacts with glucose and produces carbon dioxide, water and energy.
